How does PHP save the array as a file format? Instance Code

$file = "./cache/file.cache"; $array = Array ("color" = = Array ("Blue", "Red", "green"), "Size" = = Array ("Small", "medium", "large")); Cache File_put_contents ($file, serialize ($array));//write Cache Read-Out Cache $handle = fopen ($file, "R"); $cacheArray = Unserialize (Fread ($handle, FileSize ($file))); Copy Code The second method: Paste several functions first: Write function Cache_write ($name, $var, $values) { $cachefile = S_root. /data/data_ '. $name. PHP '; $cachetext = " " if (!defined (' Check_code ')) exit (' Access Denied '); \ r \ n ". ' $ '. $var. ' = '. Arrayeval ($values). "\r\n?>"; if (!swritefile ($cachefile, $cachetext)) { Exit ("File: $cachefile write error."); } } Arrays into strings function Arrayeval ($array, $level = 0) { $space = "; for ($i = 0; $i <= $level; $i + +) { $space. = "\ T"; } $evaluate = "Array\n$space (\ n"; $comma = $space; foreach ($array as $key = = $val) { $key = is_string ($key)? ' \ '. Addcslashes ($key, ' \ \ \ '). ' \ ': $key; $val =!is_array ($val) && (!preg_match ("/^\-?\d+$/", $val) | | strlen ($VAL) > 12)? ' \ '. Addcslashes ($val, ' \ \ \ '). ' \ ': $val; if (Is_array ($val)) { $evaluate. = "$comma $key =". Arrayeval ($val, $level + 1); } else { $evaluate. = "$comma $key = $val"; } $comma = ", \n$space"; } $evaluate. = "\n$space)"; return $evaluate; } Write file function Swritefile ($filename, $writetext, $openmod = ' W ') { if (@ $fp = fopen ($filename, $openmod)) { Flock ($FP, 2); Fwrite ($fp, $writetext); Fclose ($FP); return true; } else { Runlog (' Error ', "File: $filename write error."); return false; } } Copy Code Call: Cache_write (' file ', ' Arrayname ', $array); Include format: @include ('./data/data_cache.php '); Array reordering sort ($arrayName);
